Configuring A Scheduler Hierarchy - Juniper JUNOSE 11.1.X - QUALITY OF SERVICE CONFIGURATION GUIDE 3-21-2010 Configuration Manual

NOTE: For E Series ASIC modules, strict priority is supported only for a single first-level
scheduler node.
When determining the shaping rate, the system includes all bytes in Layer 2
encapsulations. The packets that are included in the rate depend on the Layer 2 node
that is specified in the QoS profile. For example, the shaping rate for an Ethernet
node includes bytes from the Ethernet and VLAN encapsulations.
